By extension, the episode also derives its title from the character from The Wizard of Oz.

When DoctorBeverly Crusher was caught in a shrinking warp bubble and began to realize how easy it would be to leave the bubble, she said "Click my heels together three times and I'm back in Kansas?", referencing a phrase from The Wizard of Oz, spoken by the main character, Dorothy. (TNG: "Remember Me")

The Clown quoted The Wizard of Oz from Harry Kim's memory, stating "There is no place like home" and mocked the Ensign because he was restrained and thus not able to "click his heels together three times". (VOY: "The Thaw")
